I’m about 2 weeks into flower and the new growth seems to be turning yellow and I’m getting these little brown/orange spots on the fan leaves. Can anyone tell me what this might be?
Need some help with a sick plant!!

try running some veg nutes at half with your bloom for 2 or 3 feeds see how that goes run some calmag as well if not epsom salts a 1 tbl per 5 ltr it may just be a minor ph flux or nute issue if it starts to go all over the plant worry

It is all over I probably should have mentioned that but it’s all near the top of the plant that it’s happening, I’ll test the run off tonight when I get in, and put some fresh nutes in the soil

Can this be reversed?
IF it's LSF then you can always hit it with a bio fungicide, last time I spotted it happening to me I added a fan and went all Edward Scissorhands on every leaf that showed the slightest hint of something wrong as if the affected leaves aren't there then there's no spores to transfer to other leaves. Turned out that I chopped some healthy leaves off but better safe than sorry.
I also have a habit of rotating plants so any draft is not always on one side of the plant, but I'm one of those people who only grow one or two at a time because it keeps me more "legal" here and I'm really still learning the art of growing so don't like complicating things too much. I've no idea about your set up so have no idea if you can turn the plants 90° every day like I do.

This is what my setup is like

That tells me nothing because I can't see which plant is affected, where any fans are, and so on.
IF it's LSF then knowing where everything is really is quite vital info.

Hope this helps
Dead air at sick plant, not enough air movement in that corner, add more fans for air movement due to size of space, I would do one per corner so one blows over to the next one which points to the next one, etc, so the air circulates around the whole area and is then extracted. Position of fans is critical, you see the problem on the top of the plant then you don't have the air movement necessary.
I have a much smaller area, but I still have two fans set with one low and one high so the air flow circulates across the entirety of my room, with the upper one able to be raised or lowered so it blows across the canopy depending on the plants as they grow. You need MUCH more than me because of the size of space

I've also seen your pictures in about five different threads, including some guys art thread earlier today ?
What if you get all different answers in all those different threads ? How will that help you ?
This is what the beginning of leaf septoria aka. Brown leaf spot looks like
https://www.rollitup.org/t/help-leaf-discoloration.963364/
To me yours looks more like a MAG or a Cal Mag issue but be vigilant just in case and listen to what the poster from one of your other threads told you about air circulation that's exactly what I do, sometimes in the hot weather I have two 9" fans on the floor
-good luck
*I thought I was responding to you in that other thread:
https://www.rollitup.org/t/expert-advise-needed.963562/#post-14220961
..which is another reason why starting a bunch of threads screws things up
